HMMMM HELP ???

I have a 06 5.7 here is my issue .Everytime I try to turn off MDS,rear o2,and change the axle ratio to 3.06 the car doesnt like it at all(acts like it has a stall conv. and wont turn over 60 mph at a high rpm ). Now I can just do MDS and it drives fine,without changing any of the other 2 parameters. Anyone else have that problem?????

Its the axle ratio parameter causing this.
You should not be changing that unless you have actually changed the gears. Put this back to stock.

Thanks
